BICYCLE-VISE.

SPECIFICATION forming part of Letters Patent No. 594,874, dated December '7, 1897.

Application l April 15, 1897. Serial No. 632,251. (No model.)

To @ZZ whom it may concern.-

Be it known that I, WILLIAM H. HOLMES, a citizen of the United States, residing at Oolulnbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Machines for Holding Bicycle-Tubing while it is being Operated Upon', and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.'

The object of this invention is to provide a cheap, simple, and eective'machine for use in the manufacture of bicycles, and is adapted to present a vise or clamp which is supported upon a revoluble table, certain devices being employed to form a rapid and secure adjustment of the several parts.

The invention contemplates a construction that forms a means for rigidly supporting a bicycle-frame or part thereof in order that it may be conveniently handled during the process of filing or otherwise working upon it.

Having the above objects in view, the invention consists in a vise supported upon a turn-table, mechanism for opening and closing the jaws of the vise, blocks vattached to the jaws and presenting surfaces of peculiar.

construction to engage tubes of different sizes, and means for clampin g the turn-table against rotation.

The invention further consists in the particular construction and combination of the parts which constitute the vise and facilitate its operation of engaging and disengaging the work, including other details of construction that go to make up the complete machine.

In the following specification I have entered into a detailed description of the construction and operation of my invention, reference being had to the accompanying drawings and to numerals thereon which designate the dierent parts, and what I consider to be the novel features of construction are specifically set forth in the claims.

In the drawings formin ga part of this specifcation, Figure l is a front elevation of a machine constructed in accordance with my invention. Fig. 2 is a sectional view through the vise and supporting-table therefor. Fig. 3 is a side elevation. Fig. et is a detail view of the blocks which are attached to the clamping-jaws. Fig. 5 is a detail view of one of the cam-leverswhich are employed in securing the adjustment of the parts.

Referring to the drawings by numerals, l designates a hollow column or supportingstandard, the upper end of which is bifurcated to present theidivergin'g arms 2 2, which sup- 6o port a rigid bed-plate 3, having a circular recess 4 in the upper' surface thereof. This standard and bed-plate form the supporting means for the vise hereinafter described and is ofa suflcient height to locate the said vise at the proper elevation. Upon the bed-plate, which is supported at the upper end of the column or hollow standard, is a turn-table 5, having a circular depending portion which lits within the corresponding recess or de- 7o pression in the said bed-plate, the turn-table forming the base of the vise. From the baseplate 5 extends upward the stationary jaw 6 of the vise, a web or flange 7 being provided to reinforce the lower part or shank of the jaw. The movable jaw 8 is pivotally connected to the turn-table, and .to this end the lower end of the shank of said movable jaw is embraced by the lugs or apertured ears 9 9, that extend upward from the turn-table and 8o form the bearings for a transverse pivot-pin l0, upon which the movable jaw has a rocking movement. The jaws 6 and 8 are connected to each other by a rod 11, which passes through horizontal openings in said jaws, and upon the outer end of this rod, beyond the stationary jaw, is a nut l2, held in place by a pin 13, which passes through the nut and rod. To the opposite end of the rod ll is pivoted a lever 14, having a cam-shaped end 15, 9o which bears against the outer side of the movable jaw and acts to close the same upon the stationary jaw. In the detail view it will be seen that the cam-shaped end of the lever is preferably1 bifurcated to practically present 95 two cams which engage the movable jaw adjoining opposite sides thereof, the rod lying between the cams, to which it is connected by the pivot or bearing pin 16. In connection with these jaws I provide wooden blocks 17 roo for holding the work, two blocks being used which are attached to the movable and stationary jaws, respectively. 4Each block is preferably circular, as shown in the drawings,

and is provided with a series of transverse recesses 18, which are at right angles with each other and are of different sizes, the re- Cesses in the blocks being properly arranged so as to register when the blocks are brought together and present transverse openings circular in cross-section. The blocks are also provided with axial openings I9, which are countersunk at the inner side of the block, and said openings receive thimbles 20, which encircle the connecting-rod Il, and are flanged at one end to lie within the countersunk portion of the blocks. In connection with these thimbles the stationary jaws are provided with set-screws 21, the inner ends of which engage the thimbles and thereby hold the blocks in fixed engagement with their respective jaws. By this arrangement or manner of connecting the blocks to the jaws they can be quickly manipulated to bring the openings therein at the proper position with respect to the vise by loosening the set-screws and then turning the blocks upon their axis.

In order to secure the turn-table in an adjusted position, it is provided centrally with a depending arm 22, which passes through the bed-plate 3 and receives a cam-lever 23, similar in construction to the one which operates the movable jaw, the said cam-lever 23 bearing against the under side of the bedplate between the arms 2 2 of the supportingstandard.

From the foregoing description, in connection with the accompanying drawings, the construction and operation of my improved machine for holding the tubes of bicycleframes will be readily apparent, forthe blocks are movable to bring anyone of the openings therein at the proper position, after which the lever let is manipulated to separate the jaws of the vise and is then pressed downward to clamp the tube between said blocks. The turn-table can then be adjusted by properly operating the lever 23 to release and then clamp the same. Vhen thus arranged, the machine is adj ustedto firmly hold the tubing, which may be filed or otherwise worked upon.

For convenience the turn-table 5 is provided at one side with a shelf or ledge 24E, forming the support or table to receive the tools or implements being used by the workmen in operating upon the tubing.

It will be seen from the foregoing that I have provided a machine that will be of great convenience to a workman or operator in working upon bicycle-tubing, and the parts of the device are constructed and arranged with a view to provide for a quick and convenient adjustment and also present a rigid and strong structure that will not give in use.

IIaving thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for the purpose set forth, the combination with the standard or support having a bed-plate at its upper end, of a turntable mounted upon the bed-plate and having a depending arm or member extending therethrough, a cam-lever mounted'upon the lower end of the arm and adapted to clamp the turn-table in an adjusted position, together with a vise supported upon the turntable and presenting a stationary jaw, a pivoted jaw, and means for moving the pivoted jaw to and from the stationary jaw, substantially as described.

2. In a machine of the character described,

. of the standard having a bed-plate at its up per end, a turn-table mounted on the bedplate and having a depending arm or member which extends through the said bed-plate, and a cam-lever mounted upon the lower end of the arm or member to engage the under side of the bed-plate and clamp the turn-table in an adjusted position; together with a vise mounted upon the turn-table and consisting ot' a stationary jaw, a movable jaw pivoted at its lower end to the turn-table,.a rod or shaft extending through the jaws and having a nut or stop which bears against the outer side of the stationary jaw, and a camlever pivoted to the other 'end of the rod and bearing against the movable jaw, substantially as shown and for the purpose set forth.
